Descriptor is "opp-300000000" but opp-hz value is "30000000"
missing a zero.
Fixes: a5a80f78657f ("arm64: dts: mt7622: add cpufreq related device
nodes")

This has been reported by users of OpenWrt as well, and it's an obvious
typo.
Some boards hang at reboot in TF-A bl2 when reboot happens @0.95V.
Raising the voltage to 1.00V fixes that, but this should probably be
fixed in TF-A (as Linux itself works fine with 300MHz@0.95V)
